Trump is miles ahead of other administrations in abusing it but as far back as my political awareness reaches (the Clinton admin) there have been clear awful examples like Marc Rich[1]. I certainly have a political lean but there are some really indefensible pardons on each side.
Are you equating Trump's pardons and commutations to Bidens? For review, Biden's were largely for non-violent drug offenders and preemptive pardons for people like Anthony Fauci and federal employees prosecuting Jan 6 defendants and the like.
Save for his pardon of his son Hunter (who's own prosecution was littered with politics), Biden's were largely pedestrian.
Yes actually. As far as I'm aware even the President can't pardon crimes someone may commit in the future. Can you point out the ones where he did that?
